Abstract Details

2008, Doctor of Philosophy, University of Toledo, Electrical Engineering.
This dissertation investigates the optimal call admission control (CAC) policies for Non Priority Scheme (NPS) and Reserved Channel Scheme (RCS) in wireless cellular networks for the following cases: 1. Homogenous traffic in a cell; 2. Multimedia traffic in a cell; 3. Homogenous traffic in a network; 4. Multimedia traffic in a network. Both new call and handoff call arrival processes are assumed to be Poisson processes, and the call holding times are exponentially distributed with different rate for new calls and handoff calls. Admitting each call would bring a reward to the network provider but holding each call in the system would also incur some cost to the provider. This dissertation focuses on the optimization problem of when to admit or reject a call in order to achieve the maximum reward. By establishing an infinite horizon discounted Semi Markov Decision Process (SMDP) model, this research verifies that the optimal policies of all the four cases mentioned above are state-related control policies for NPS as well as RCS. More over, this research also finds that optimal control policy for Case (1) above is still state-related control policy even if the combined arrival process for new and handoff calls are described by General Distribution. The numerical results presented in this dissertation in both tables and diagrams for all of the above cases are consistent with the theoretical results derived.
